Description

Technical Field

[0001] The utility model relates to the technical field of current collectors, in particular to a current collector carbon brush assembly. Background Art

[0002] The collector is an electrical component that is widely used in the mobile control systems of various large-scale machinery and equipment, mainly used to transmit electrical energy, signals and data. The collector has different applications and names in different fields. For example, in electronic devices, the collector can be used as an electrode to collect electrons, while in generators, the collector is a device that converts the generated alternating current into pulsating current. In the busbar system, the collector directly transmits electrical energy to the electrical appliance through the sliding contact between the collector brush and the guide rail, realizing the mobile power supply of the system. The collector carbon brush block is the conductive part of the collector. The collector copper brush made of electrolytic copper and other alloy materials using powder metallurgy technology has good wear resistance and excellent conductivity. It not only ensures the safety of electrical equipment, but also can effectively transmit power, while running smoothly and with low noise.

[0003] For example, the Chinese patent publication number CN208173971U, "A Carbon Brush Collector", discloses a carbon brush collector, which relates to the technical field of electrical equipment. The carbon brush collector includes a mounting seat, a support rod, a movable rod, a collector brush and an elastic connector. The interior of the mounting seat is provided with a mounting groove. The support rod is located in the mounting groove, and the support rod has a relative mounting seat connecting end and a first movable end, and the mounting seat connecting end is connected to the mounting seat. The movable rod has a relative second movable end and a collector brush connecting end, and the first movable end is rotatably connected to the second movable end. The collector brush is detachably connected to the collector brush connecting end, and the collector brush is detachably connected to the collector brush connecting end. One end of the elastic member is connected to the support rod, and the other end of the elastic member is connected to the collector brush. The carbon brush collector can make up for the shortcomings of the small number of existing collectors and meet the needs of equipment.

[0004] However, in actual use, it is inconvenient to disassemble and assemble. The carbon brushes of the collector will constantly contact and wear during use. It is not convenient to disassemble and assemble the carbon brushes of the collector, and it is not convenient to maintain and replace parts of the carbon brushes of the collector. Therefore, a current collector carbon brush assembly is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a collector carbon brush assembly in view of the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a collector carbon brush assembly, including a collector body, a slide rail fixedly connected above the collector body, a sliding seat slidably connected above the slide rail, a brush mechanism is arranged above the sliding seat, a fixed assembly is arranged on the front of the sliding seat, the fixed assembly includes a mounting plate, the mounting plate is fixedly connected to the front of the collector body, a guard plate is fixedly connected to the front of the mounting plate, a fixing plate is movably fitted between the guard plate and the mounting plate, the fixing plate is fixedly connected to the front of the sliding seat, an insertion assembly is arranged on the front of the fixing plate, the insertion assembly includes an insertion block, the insertion block movably penetrates the guard plate and the front of the fixing plate, the insertion block is plugged into the front of the mounting plate, and a safety assembly is arranged on the left side of the insertion block When it is necessary to disassemble the brush mechanism, first pull the top plate toward the front so that the top plate drives the plug block to be pulled out from the front of the mounting plate and the fixed plate. As the plug block moves toward the front, it will drive the toggle lever to toggle the baffle toward the front, and the baffle will move away from the left side of the fixed plate. At this time, the plug block will also cancel the fixation of the fixed plate. By sliding the sliding seat to the left on the slide rail, the fixed plate can be passed through the opening on the left side of the baffle plate to remove the sliding seat, thereby achieving the purpose of disassembling the brush mechanism. When it is necessary to install, align the sliding seat with the left side of the slide rail and insert it. As the sliding seat moves, pull the top plate toward the front to prevent obstruction by the plug block and the baffle bar. When the sliding seat slides into place, by loosening the top plate, the plug block will fix the fixed plate, and the baffle bar will also block the left side of the fixed plate to fix the sliding seat, thereby achieving the purpose of installing the brush mechanism.

[0007] Preferably, the insertion assembly further comprises a top sheet, the top sheet is fixedly connected to the front side of the insertion block, and a first spring is elastically connected between the top sheet and the guard plate.

[0008] Preferably, the insurance component includes a support plate, which is fixedly connected to the front of the guard plate, and the right side of the support plate is rotated by a torsion spring and elastically connected to a baffle bar, a toggle rod is movably fitted under the baffle bar, and the toggle rod is fixedly connected to the top of the plug block.

When the distance between the power supply rail and the collector body changes, the second spring will be compressed or released, and drive the telescopic strip to be able to extend and retract above the telescopic sleeve, so that the bearing seat can be raised and lowered according to the distance between the collector body and the power supply rail, so that the carbon brush body can fit the power supply rail. When the angle of a part of the power supply rail changes, the carbon brush body will adapt to the angle under the action of the articulated seat, and the elastic sheet will also exert elastic force to make the carbon brush body fit the power supply rail, thereby ensuring the flexibility of the carbon brush body.

[0012] The utility model adopts the above technical solution, which can bring the following beneficial effects:

The torsion spring 702 will apply a torsion force in the left state to make the baffle 703 lean on the guard plate 502. At this time, the baffle 703 will block the left side of the fixed plate 503, and a toggle rod 704 is movably fitted under the baffle 703. The toggle rod 704 is L-shaped and fixedly connected to the top of the plug block 601.

[0021] Working principle: When the brush mechanism 4 needs to be disassembled, the top sheet 602 is first pulled forward, so that the top sheet 602 drives the plug 601 to be pulled away from the front of the mounting plate 501 and the fixed plate 503. As the plug 601 moves forward, it drives the toggle lever 704 to toggle the baffle 703 forward, and the baffle 703 moves away from the left side of the fixed plate 503.
